The Wheelman Pro is designed to be used on one tractor. The Pro replaces the vehicle steering wheel and mounts to the Spline of the steering column.
The Wheelman Flex is movable and uses the tractor's existing steering wheel. Two rings clamp onto the existing steering wheel, allowing the Flex unit to be moved from one tractor to another.
Performance is comparable between the units, but the Wheelman Pro has slightly higher torque so is recommended for heavy steering tractors or tractors without power steering. If the manual operation of steering is working well, you would be OK with a Flex unit.
